Nodular cast iron pipe with multiple groups of anticorrosive coatings and preparation method of nodular cast iron pipe
The invention discloses a nodular cast iron pipe with multiple groups of anticorrosive coatings and a preparation method of the nodular cast iron pipe, and belongs to the technical field of pipeline anticorrosion, the nodular cast iron pipe comprises a nodular cast iron pipe body, a lining layer coated on the inner surface of the pipe body, and a metal layer, a wetting transition layer, a mortar layer and a sealing layer which are sequentially coated on the outer surface of the pipe body from inside to outside. The coating has high weather resistance, corrosion resistance and wear resistance, and the service life of the pipeline can be effectively prolonged.
本发明公开了一种具有多组防腐涂层的球墨铸铁管及其制备方法，属于管道防腐技术领域，包括球墨铸铁管的管体、涂覆在管体内表面的内衬层以及由内到外依次包覆在管体外表面的金属层、润湿过渡层、砂浆层与封闭层。本发明具有较高的耐候性、防腐性以及耐磨性，能够有效延长管线使用寿命。
